Fixed, as follows.
1) Changed the default value of displaystyle on mtable to
"inherited (false)".
Added text to describe that mtable makes an automatic change of the
value of displaystyle to "false" if the attribute is not present.
2) Added text to describe that mscarries makes an automatic change of
the value of displaystyle to "false".
3) Changed the default value of scriptsizemultiplier on mscarries to
"inherited (0.6)".
Added text to describe that mscarries changes the default value of
the inherited scriptsizemultiplier to 0.6. The effect is that the
inherited value should override the default value, but the default
value, inside mscarries, should be 0.6.
